The Ferds Security contains methods that help you create a secure application, processing input data for security. Ferds Security has several functions to support your security such as :
Now, let’s describe the features:
$ npm install ferds-security
Escaping a string means to reduce ambiguity in quotes (and other characters) used in that string. For instance, when you're defining a string, you typically surround it in either double quotes or single quotes:
"Hello World."
Now I have ambiguity - the interpreter doesn't know where my string ends. If I want to keep my double quotes, I have a couple options. I could use single quotes around my string:
'Hello "World."'
Or I can escape my quotes:
"Hello \"World.\""
Any quote that is preceded by a slash is escaped, and understood to be part of the value of the string.
If you using Ferds Security, the usage of escape string will be very simple like this :
var text1 = "Hello \"World.\"";
var text2 = 'Hello "World."';
var text3 = "Hello World.";
var escape_text1 = security.escape_string( text1 );
var escape_text2 = security.escape_string( text2 );
var escape_text3 = security.escape_string( text3 );
console.log( escape_text1 );
console.log( escape_text2 );
console.log( escape_text3 );
The results will be like this :
Hello \"World.\"
Hello \"World.\"
Hello World.

If we read the that's quote, yes, that's right quote. But, we can set a small prevention for attacker with great password. You can use password_strength_meter function to give you information about the strength of the password. The function will be simple like this :
var strength_password1 = security.password_strength_meter( "ABCDZ" );
var strength_password2 = security.password_strength_meter( "ABCDZ!@#123_~KWJFKWJFKJWFK*@&$(@&" );
console.log( "The strength of the Password 1 is " + strength_password1 );
console.log( "The strength of the Password 2 is " + strength_password2 );
Results :
The strength of the Password 1 is 25
The strength of the Password 2 is 100
This is some criteria of strength of your password :
Score | Description |
---|---|
0 - 25 | Very Bad |
26-50 | Weak |
51-75 | Good |
76-100 | Strong |
To prevent the Cross Site Scripting, you can use three ways :
Okay, now we will try to prevent Cross Site Scripting with Sanitize function. Examples of simple use :
var security = require( 'ferds-security' );
var text = '<script>alert("XXX");</script>';
var sanitize_text = security.sanitizer( text );
console.log( sanitize_text );
The results will be like this :
<script>alert("XXX");</script>
